Three-dimensional molecule editing techniques and structural optimization using semiempirical PM7 Hamiltonian [4], and molecular docking were used to predict in silico the interaction energy between Ops pesticides and fullerene derivatives, designed based on AChE active site, as target to the organophosphates compounds, to describe in molecular level the interaction of Ops with proposed molecules.
All of the geometry optimizations were performed by semiempirical PM6 [28, 29], ab initio Hartree-Fock (HF/6-31Gdp) and density functional theory (DFT) M06-2X/6-31Gd methods [30] in the gas phase.
